'. It is a principal object of this invention to provide a conveyorsystem that will operate on an overhead track to carry feed to thevarious stalls. 7

Other objects will appear to those skilled in the art from a reading ofthe, following specification. The accompanying drawings illustrate apreferred embodiment of the invention, and it is under.- stoodthat'modifications, may be made therein without departing from thespirit of the invention as hereinafter claimed. H

Figure 1, represents a schematic View, notin proper proportion, of aconveyor system constructed accordance Withthe principles of, theinvention.

Figure 2 is an elevation of a portion of the conveyor, showing themanual means for moving the material, taken along the line 2-2 ofFigure 1. 7 v

Figure 3 is a horizontal section taken along the line 3-3 of Figure 1. v

Figure 4 is a front view of the bucket or carrier in tipped or openingposition. 7 I s Figure is a side elevation of the bucket or carrier inclosed position, taken from the right ofFigure4.;1 h V The barn or otherenclosure is represented in; the drawings as having two walls I I andI2, An overhead track I3, which may comprise a rail or a rod, isfastened from wall II to the other wall I2. This track I3.is adapted tocarry-the bogie [4 of a singlebucket or carrier I5. The cable 20 isfastened, at one end ZI tothe bogie l4, and after passing around thevariouspulleys and other instrum-entalities to be described more fullyhereinafter, is attached at the other end 22 .to the bucket l5.

- As indicated in Figure 1,.the cable 20 leads from the bogie I4 arounda pulley 26 on the wall [2, back to apulley 21 on the wall II, downaround a manual pulley 30, over a pulley 3I, over an idler pulley 32 onthe bogie I4, and back tolthe bucket I'5.; llf desired, the bogie I4 maycomprise a pair of idler pulleys 36 and 31,'-and the wall II may alsoinclude idler pulleys 38 and 39. The cable 20 islso designed that it hasa minimum of slack.

It will be apparent,.therefore, that since the distances between theterminal pulleys 30 and 21 and 25 are fixed, tension on the cable 20anywhere along-,itslength willact to ove the bucket I5 in one directionor the other. v 7

The manual pulley supports a, @rank M1 by which, the; pulley m-ayxberotated. Clockwise rotation ofntheo ank- 40, from the position indicatedin Figure '1 of the drawings, will pull the bucket I5 to the left, androtation of the crank 40 theoppOsite direction will pull the bucketl5totheright. g

A dditionalpulleys, such as 43 and A l, may be provided to reducefriction of the cable 20. Th ulley 3| is mounted at; the upper end of averticalrod 50, which is ad'apted to slide vertieally in a horizontalbracket 5| supported on the wall II. The lower end of the rod is pivotedto an arm 52, which itself is pivoted to the wall II. The arm 52 islinked to, a foot pedal 54, likewise pivoted to wall II by a link 55. Itis obvious, ,therefore that the arm 52 and the foot pedal 54 will havesubstantially parallel movement about their respective pivots on thewall II.

p The bucket I 5 comprises a container of any desired shape or size. Thebucket I5 is pivotally supported by a bifurcated bracket depending fromthebogie I If The end 22 offthe cable 20 is attached to a-lug 62 at oneend of the bucket I5. Consequently, if the end 22 of the cable 20 ispulled upwardly, the lug 22will also be pulled upwardly and tiltthebucket I5 about the pivotal supporter the bracket 30. The other endofthe bucket I5 comprises a tail 65 and two side exten sions BB'fiXedtothe tail '35." The tail 65 and the side extensionstfi are pivoted withrespect to the body of the bucket I5 by means" of two or more curvedhinges; Two'links I0 arepivoted to the'sides of "the bucket I5 adjacentthe lug '62-, and are connected to the bifurcated bracket 60 by means oftwo links II and a horizontal rod-'|2. Theother ends of the links-"I0are connected to the top of-th tail 65 by means of a pair of links 14-.In operation of the conveyor system, the bucket l5- isloaded with feedor other desired materials to be transported. The bucket I5 is normallyin a closed position, as shown in Figure 1 of the drawings? Rotationofthe crank will move the conveyor bucket l5 along the track I3to-anydesired location, 1 If the system is used in a barn; the track I3 maybemarkedwith a plurality of indicia indicating particular stalls oranimals. If desired these indicia may be ,colored' to be more readilyvisible from a distance. It is understood, of course,-that' there may beas many stations along the track l3 as is desired, and that the perat il t nd at the wall 11,. and turn the.

crank 40 to move the bucket I5 anywhere along the track l3. r, the cableitself may be marked.

When the bucket l has reached its desired location, the operatordepresses either the arm 52 or the foot pedal 54. This will move up therod 50, thereby elevating the movable pulley 3|. The movement of thepulley 3| will exert a tension on the end 22 of the cable 20. The lug 62will be moved upwardly, tilting the bucket l5 clockwise. The bracket 60depending from the bogie I4 will remain vertical, and by virtue of theconnecting link II the link pivoted on the bucket l5 will transmitmotion through the link 12 to move the tail 65 clockwise, as indicatedin Figure 4, to dump the material. As soon as the required amount ofmaterial has been dumped atthe desired location, the operator willrelease the arm 52 or the foot pedal 54, thereby restoring the bucket I5to its closed horizontal position. 'The bucket l5 can then bemanipulated to another station and the I dumping operation r'epea'ted.
